Questions KIQ.005 “How often do you have urinary leakage? Would you say …” and KIQ.010 “How much urine do you lose each time? Would you say…” comprise the Incontinence Severity Index (Sandvik, 2000). This index, based on information about frequency in four levels and amount of leakage in three levels, can be multiplied to obtain an index value (1-12). The four-level severity index is based on the following index values: 1-2, slight; 3-6, moderate; 8-9, severe; 10-12, very severe.

Eligible Sample

The target sample for the questions in this section is adults 20 years and older.

Interview Setting and Mode of Administration

Questions on kidney disease, dialysis, kidney stones, and passing a kidney stone (KIQ022, KIQ025, KIQ026, KID028) were asked in the home by trained interviewers using a Computer-Assisted Personal Interviewing (CAPI) system.

Data Processing and Editing

Frequency counts were verified during the preparation of the file.

Analytic Notes

Missing data

Although KIQ005 – KIQ480 were targeted to all participants 20 years and older, data for these questions are missing for 9.6% of individuals who completed the household interview, but did not complete the MEC CAPI.

Appropriate sample weights

Interview weight: KIQ022- KID028

Examination weight: KIQ005-KIQ480

The interview weight should be used when an analysis uses data only from the household interview. If an analysis uses data from the MEC (MEC interview, examination, or laboratory data) exclusively, or in conjunction with the household interview data, the examination weight should be used.
